MATTHEW MORIARTY, OF BANGOR, MAINE.

CESSPOOL.

SPECIFICATION forming part of Letters Patent No. 498,287, dated May 30,1893.

Application filed August 26, 1892.

T0 at whom it may concern.-

Be it known that I, MATTHEW MORIARTY, a citizen of the United States,residing at Bangor, in the county of Penobscot and State of Maine, haveinvented new and useful Improvements in Oesspools; and I do herebydeclare that the following is a full, clear, and exact description of myinvention, which will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to new and useful improvements in cesspools andconsists of an outlet or overflow connection so constructed and arrangedas to form a cleanout-opening whereby the contents of the cesspool canbe pumped or bailed directly into the drain en tering into themain-sewer; and it also forms a trapped outlet to prevent gasesgenerated in the sewer from entering the cesspool (thereby making thewater foul) and from there ex-. tending into the street.

The object of my device is to provide suitable andconvenient means forcleaning out a cesspool within the same and obviate the necessity ofbailing the foul water into carts and hauling the same through thestreets as has been the usual method. This object is accomplished in thefollowing manner by the aid of my invention throughout the descriptionof which reference is made to the accompanying drawings forming part ofthis specifica tion, in which- Figure 1 represents a sectional elevationof a cesspool and its adjoining drain provided with my improved outlet.Fig. 2 is a perspective view of the case of my improved cesspool-outletwith its covers and valve removed to show construction. Fig. 3 shows asimilar view of the end door of my device. Fig. 4 is a similarprojection of the swing-valve used in my device. Fig. 5. is an isometricview of my device showing the swing-valve in position and thecleanout-oover removed, a portion of the case being cutaway to showinterior. Fig. 6. is an isometric view of the cleanout-cover of mydevice.

Similar letters of reference refer to correspondingly like partsthroughout the several figures.

My device may be constructed of either wood or metal but the lattermaterial I consider preferable on account of its lasting Serial No.444,180. (No model.)

qualities and I will therefore describe it as manufactured from such.

In the drawings 0, refers to acesspool which is made in the ordinarymanner and forms a catch-basin with an outlet considerably above itsbottom, with a connecting drain 13, entering the main sewer A.

It is in the outlet of the cesspool C that my device is placed and itconsists of a box like case D having a flange h, cast thereon aboutmidway of its length. This case D is constructed with an open end 0,which is inserted into the drain B at the outlet 'of the cesspool 0, asfar as the flange h,and entirely fills or closes the outlet. Theopposite end of the case D, is closed with the exception of a smallopening G, into which a door G is fitted, and this opening G need beonly sufficiently large to allow a rod to be inserted therein for thepurpose of removing any 0b struction that would be liable to clog thedrain B.

At the top of the case D is a large opening F, (which I shall term thecleanout-opening) fitted with a tight cover F; and directly under thiscleanout-opening is another large opening I, which serves as an inletfor. the overflow or excess of water in the cesspool O.

Extending diagonally across the interior of the case D and hung from theupper corner of its closed end is a swing-valveE hinged in such manneras to entirely cover the inletopening I. A rib f, cast upon the interiorof the case D, and extending entirely around the same formsa seatagainst which the valve E closes. This swing-valve E, forms a watershedfor the purpose of diverting the water which is poured in to thecleanout-opening F, over the inlet opening I, when cleaning out thecontents of the cesspool. And it servesa double purpose, for when thecover F, is put on it immediately traps the drain B and preventssewer-gases from entering the cesspool even when the latter isempty.

It can now be readily understood that when a cesspool is provided withmy device the water within the same will stand as high as the top of thelower rib f, of the valve-seat, before it will run into the drain B,consequently the inlet-opening I, is under water and neces sarily sealedagainst the escape of sewergases. A further seal is obtained through theswingvalve E which always remains closed upon its seat until the waterin the cesspool O attains sufficient height to raise the valve andescape through the drain B. The object of this swing-valve E, was not toobtain a gas-check to prevent the escape of sewer-gases, although itassists the submerged inlet in accomplishing that result, but itsutilization was for the purpose of closing the inlet opening I, anddirecting the course of water bailed into the cleanout-opening F whenfound necessary to clean out the cesspool. The cover F, of thecleanout-opening F can be sealed absolutely tight by having its edgescast to fit within grooves around the edge of the cleanout-opening. Thena little water poured upon the topof the cover would fill the groovesuffieiently to close the intervening space between the cover a and topof case D.

Having described my invention, what I claim, and desire to secure byLetters Patent of the United States, is-

1. A cesspool outlet consisting of a case D having its open end and aportion of its length inserted in the outlet drain, said case having itsopposite end closed and an inlet opening from its under sidenextadjacent its closed end, a swing-valve extending from the uppercorner of said case diagonally across the inlet opening, and acleauout-opeuing provided with a cover, directly above said swing-valve,all for the purpose described and substantially as shown and set forth.

2. In combination with a cesspool and its connecting sewer-drain theimproved outlet connecting the cesspool with said drain, consisting of acase D having its open end 1nserted in said drain and its opposite endMATTHEW MORIARTY.
